In addition to a semi Olympic-size pool and administrative offices, the Beloeil Aquatic Center includes a sauna, a recreational pool, a beach, a children’s wading pool and slide as well as stands for the competition pool. All facilities provide universal accessibility. Traditional locker rooms have been abandoned in favour of changing rooms with family transition areas.

The structure of the basins is made of poured concrete on pile foundations coated with a release film to avoid overcompression due to consolidation over time of the surrounding clay. The above-grade floors of the project are steel framed.

A multitude of energy-efficient measures have been adopted, such as micro filter ceramics and UV dechlorination, offering increased performance while reducing energy consumption. Mechanical systems also benefit from geothermal energy. The orientation and geometry of the building were chosen to maximize natural sunlight. A white roof allows the reduction of heat islands. Finally, a rain recovery system allows its recycling into greywater for sanitary appliances.

The various energy-saving measures save $ 150,000 annually and 750 tons of CO2 a year.


Technical challenges :

  • Design-build project involving an integrated team of structural, architectural, and MEP professionals along with design-build specialty trades for the principal components.
  • Predetermined maximum price tender required continual optimization of all building systems in order to secure the successful bid.
  • 43 m (140 ft) deep clay soil conditions with additional 1.5 m (5 ft) of fill added to raise the site were challenging issues to support heavy structures such as the FINA Short Course Olympic competition pool, the recreation pool, and various pool reservoirs.
  • Our work included the feasibility analysis of conventional foundations as well as light-weight styrofoam fill options to narrow in on the most reliable and cost-effective foundation design.
  • Complex formwork for the various pool basin configurations combined to the integration of the filtration and water circulation systems.  

Notable solutions and innovations :

  • Mixed foundation system consisting of a pool base raft 600 mm (24 in) thick atop driven steel piles.
  • All of the project's slabs on grade were structural to be supported on piles due to poor geotechnical conditions.
  • In order to alleviate the effects of negative friction on the piles owing to addition of fill loads at the surface of the soil, an economical solution using a non-adherent coating on the pile shafts was coordinated between the structural, geotechnical, and pile subcontractor.
  • Heavy use of BIM enabled the production of drawings of complex concrete surfaces to simplify the formwork.
  • Use of high-volume Styrofoam fill in void spaces to simplify the creative concrete shapes in the recreational pool.
